Simultaneously solve cost reduction and environmental protection! A construction method that can directly reach existing manholes.
The "Hume Pipe Pushing Method" is a pushing method that allows direct access to an existing manhole shield when the target shaft cannot be excavated or is undesirable to excavate. The excavation machine's outer shell is made of CPC steel pipe (Chemical Prestressed Concrete Steel Pipe), and the necessary driving equipment for excavation is incorporated in a recoverable state. After reaching the target, only the built-in equipment of the excavation machine is recovered, while the outer shell remains as a pipe (structure). 【Features】 ■ No need for construction costs for the target shaft and cutting edge excavation work ■ Cost reduction ■ Environmental protection ■ Avoidance of total loss of the excavation machine For more details, please feel free to contact us.

Company information
Our company was founded in 1958 and specializes in underground special civil engineering works such as underground continuous walls, underground obstacle removal, ground improvement, and pipeline construction. In recent years, we have expanded our business operations to include slope work and construction. There is a growing social demand for securing the natural environment, seismic reinforcement, liquefaction prevention, restoration of structures, and urban redevelopment, which have become pressing issues in recent years. In response to these social needs, we have developed seismic reinforcement and liquefaction countermeasure methods such as the "Ultra Multi-Point DP Method" and the "High Grip Grout Method." For structural restoration, we utilize our in-house developed restoration method called "Suiheikun," and for urban redevelopment, we are conducting research and development of new methods such as the "Hiro Work Kmigty Method," "Bauer Method," and "Super Top Method," aimed at underground obstacle removal. Additionally, as part of our eco-friendly initiatives, we are researching and developing methods that use bubble drilling fluid to reduce industrial waste, striving to contribute to society through high-quality construction and services. We aim to continue responding to the needs of the times by deploying a variety of specialized techniques and uniquely developed methods.
